How this service works
Get recent trades for a Polymarket prediction market. Trades are decoded from on-chain OrderFilled events on Polygon, joined with market metadata. **What it helps to answer:** 1. **What are the most recent trades in this market?** 2. **Who is buying and selling, and at what prices?** 3. **What is the trade size distribution?**
Output
A paginated array of trade records, each containing market_id, buyer and seller wallet addresses, price per share (0-1), trade size in tokens, USDC value, outcome side (Yes/No), outcome index, taker action (buy/sell), transaction hash, and timestamp. Also includes pagination metadata (current page, per_page, is_last_page).
